Specification of Letters Patent.

Application filed March 25, 1909. Serial No. 485,846.

Toall whom it may concern:

Be it known that I, CARL W. Wnrss, a citizen of the United States,residing in the borough of Manhattan, .of the city of New York, in theState of New York, have invented certain new and useful Improvements inMotors, of which the following is a speci fication, reference being hadto the accompanying drawings, forming a part hereof.

The invention relates generally to rotary motors of the type known asgas turbines, in which the rotor is driven at high speed by the impactor the reaction, or by both the impact and the reaction, of products ofcombustion delivered at high veloclty through suitable nozzles. In thisinvention,

- however, the rotor is driven by the move-" ment of the working fluidout of and into the chambers of the rotor, between the driving bladesthereof, under the influence of successive variations, of pressure inthe chambers of the'rotor due to successive heating and cooling of theworking fluid in such chambers. this description proceeds, that theoperations herein described mightfibe' carried out in any of manydifferent structures, and therefore it is to be understood that althoughthere is illustrated and described herein a' structure which appears nowto be the best practical embodiment of the invention, nevertheless suchconstruction is to. be regarded as merely illustrative of the nature ofthe indicated by the line 33 of Fig. 1. Fig' 4 is a view in elevation ofthe rotor, with a portion thereof broken out to show the arrangement ofthe blades.

The embodiment of the invention shown ments, a back orsupporting platea, a main It will be obvious, especially as casing b, which is securedto the back or supporting plate a, as by bolts a, a shaft a mounted torotate in suitable bearingsin theback plate a and in a boss or sleeve dwhich is "carried by andfvirtually forms a part of easing b, and a rotorc which is suitably secured to the shaft 0. The casing b is shown ashaving a flange Z) through which the en tire motor is supported upon asuitable pedestal or base. The rotor e, in the construction shown,consists of a circular plate or disk 6, an annular ring 6 parallel withthe plate 6, a series of driving blades 6 secured between the plate 6and the ring 0 near the outer periphery of the ring 6 and a series ofblades e*, which divide the space between the ring e and the plate intoan annular series of chambers 6 each. of such chambers preferably havingat its outer margin a plurality of driving blades 6 To reduce leakage asmuch as possible the face of the rotor is formed with annular ribs 6 andintervening grooves, which coEipera-te with corresponding ribs andgrooves on the adjacent face of the main casing b, as clearly shown inFigs. 2 and 3. I

For convenience in construction, the main casing b is generally annularwith respect to the axis of the shaft 0, comprising a substantially flatannular plate 5 an outer arched wall Z2 and an internal arched wall 7),erected upon the plateb 'and receiving with .a free working fit theprojecting portion of the rotor which is composed of the ring 6 and theblades 6 and 6*. A water jacket 71 is provided for a portion of theshell or casing 73.

It will be understood, especially by reference to Fig. 1, that the wallsreferred to are not continuous but are so formed and disposed as toprovide certain chambers, passages and' ports with intervening wallswhich will be more particularly referred to herein after, such chambers,passages and ports, with the intervening walls. being mainly related tothe annular chamber f formed in blades-c and e of the rotor travel. Thearrangement of these chambers. passages and ports will be more readilyunderstoodin connection with the description of the ac- Patented Nov.22,, 916).

or by the shell or casing b and in which the tions or functions whichtake place or are accomplished, as hereinafter explained, but

it will first be pointed out that-in or adjacent to one of such chambersthere is located a source of heat, represented by a burner tube g with afuel injector g and a suitable ig- 'niter 9 The air which, successivelyheated and cooled, forms the working fluid, enters the motor through thechannel h and immediatelyfills the chambers e at atmosphericpressure,free assage for the air beyond the rotor being a orded throughthe'openin it. As will be understood, the induction 0 air at asufiicientlyrapid rate to meet the requirements of the motor, when themotor is in operation, is promoted by centrifugal force. Each volume ofair, measured by the capacity of the chamber a, is immediately cut offfrom communication with the-outer air by the passage of the containingchamber between the walls h and h a nozzle. .hf being convenientlylocated in the Wall h through which steam may be admitted from the upperportion of the water jacket 6 under control of a suitable regulatingvalve 72.. Suchvolume of air originally at at- 'mospheric pressure andnormal temperature,

' is transferred to the chamber is in which the i. vicinity ofv thesource of heat may exert its.

volume of air is expanded by heat, a source of heat 9, already referredto, being located in or ad acent to this chamber, preferably in theportion of the chamber on the inner In order that ad-' side of the rotorblades. vantage may be taken of the expansion of the air the sourceofheat1g is preferably "located near the farther end or. exit port, of

the chamber, the wall h is extended angularly beyond the wall If, and anozzle I0 is formed in the end of the chamber is nearest to the openingit, so that the air which is expanded and has its pressure raised in theforce through the nozzle 70 upon the blades 6? of the chamber which hasust come into communication with the chamber is and in which the air isnear the normal temperature andv therefore near the normal atmosphericpressure, the volume of steam admitted through the nozzle A beingrelatively small and therefore having relatively little efiect inraising the temperature or the pressure.

From the chamber is, is each chamber 6 of the rotor passes in successionbetween between the blades 6 acting upon the blades r and adding itsimpulse to the rotor. The

port 1 is immediately succeeded, in the continuedmovement of'the.chamber with the;

rotor, by a wall I which confines the now rarefied 'volume of workingfluid in the chamber, cutting it ofi from communication with theatmosphere. During the passage of the chamber between the walls Z and Zthe temperature of the confined volume of working fluid remainspractically at its maximum and the pressure thereof is prac' ticallyatmospheric. The chamber thus con-. taining working fluid at hightemperature but normal pressure now moves into the cooling or condensingchamber m, m in which the temperature is relatively low since sov thechamber is surrounded byv the water jacket. The cooling of the containedvolume of air causes an immediate fall in the pressure and anequalization of pressure in the chambers e and the chamber m, m. Thewall Z is extended angularly beyond the wall l -so that the movement ofworking fluid ii each cliamber 6 as it first comes into communicationwith the chamber m, is outward between the blades 6 Such working fluidtherefore acts upon the bladesa'nd its force is, therefore, added to theimpelling force which drives the motor.

The volume of air contained in each chamber e is successively cut offfrom the chamber m, m by passage between the walls 11., n and is thenplaced in communication. with the atmosphere through the port n The Wall19. is extended angularly beyond the port 17. and. since the volume ofair contained in each chamber 6 after leaving the chamber m,,m, is atpractically normal temperature and is below normal or atmosphericpressure, the equalization of pressure is estab-.

lished by an inward movement of air through the ort n into the chamber 6between the bla es' 6 The inwardlys moving air acts upon the blades aand its force is, therefore,

also added to the impelling force oftherotor. i I Beyond, the port aeach chamber 6 in succession, passes between the wall 71. and the wall ainto communication with the passages or openings h, h, in which thecycle of operation already described isbe'gun over again. I I v I Itwill be seen that in the transfer and displacement of working fluid-inany given chamber of the rotor at successive points in its movementabout the center of revolution, the working fluid, in its successiveexpansion and contraction, acts upon the-blades or vanes of the rotor,yielding the driving.

impulse. it will also be seen that the volume of working fluid containedin each successive chamber 6 is first subjected to compression in thechamber through the action thereon of the air or gases of the chamber inthrough the passage or nozzle k while the inner mouth of the chamber astill remains erases closed by the wall If. -Again whenrapid is promotedby centrifugal force and the displacement of air from thechambers e as.in

succession, they reach the port Z, is likewise promoted by centrifugalforce.

The chambers, ports and walls with the source of heat and the coolerconstitute means for the successive expansion and contractlon of theworking fluld transferred from point to point in the chambers 6 oftherotor and means for compelling or directingthe movement of the workingfluid inward or outward between the blades of the rotor so that theforce thereof shall act upon such blades, and it will be obvious thatthe form and arrangement of such means mightbe variedwidely withoutdeparting from the spirit of the invention.

For convenience, the chamber m is shown as connected by. a pipe 0 with apump 0',

operated by an eccentric 0 on the shaft 0, for the purpose of drawingoff from the chamber m the water of condensation. Likewise the fuelinlet nozzle'g is shown as provided with a controlling valve g? whichmay be operated in usual manner by a suitable governor g, on the shaft 0forthe pur pose of regulating the admission of fuel.
